Biomolecules & Polymers

5 interactive Chemistry simulations on biomolecules & polymers.

Chemistry · Biomolecules & Polymers Amino acids: ionic forms with pH, isoelectric point and peptide bonds In ion mode, drag the pH slider from 0 to 14 and watch the amino acid's structure change instantly — a cation in acid, a zwitterion near... Ages 17–18
Chemistry · Biomolecules & Polymers Carbohydrates: structure, hydrolysis and identification reactions Choose glucose, fructose, sucrose, starch or cellulose, and the simulation draws the matching number of linked rings (one ring, two... Ages 17–18
Chemistry · Biomolecules & Polymers Protein coagulation and the biuret test Five test tubes of egg-white solution are heated or treated with HCl, ethanol and CuSO₄, and the fifth undergoes the biuret test (NaOH +... Ages 17–18
Chemistry · Biomolecules & Polymers Addition polymerisation: monomers joining into a polymer chain (PE, PP, PVC, PTFE, PS) Monomer molecules with a C=C double bond (ethylene, propylene, vinyl chloride, tetrafluoroethylene, styrene) move freely; as... Ages 17–18
Chemistry · Biomolecules & Polymers Fat saponification and how soap micelles clean Saponification mode: a fat molecule (a glycerol backbone plus three fatty-acid residues) is cut by OH⁻ ions at its three ester bonds,... Ages 17–18
